t 18 Claims.

The invention relatesto a method of cutting and forming the parts of toys and other articles fromcardboard.

An object of the present invention is to provide 5 a method of manufacture by which the advantage of cutting figures or elements and the formation of bending crease'lines may be obtained .by the use of ruled dies so that the figures of mechanical toys and the operating mechanism thereof involving intricate patterns may be easily and cheaply produced from cardboard. l

A further object of the invention is to provide a method by which bending, folding andv 'shaping operations subsequent to the cutting and'crease line forming may be accomplished with accuracy and great facility and without the liability of rupturing and tearing the parts.

A further object of the invention is to provide' a method of bending and shaping cardboard and be located interiorly of the article and concealed from View in the completed article and by which method continuous layers of cardboard will be arranged exteriorly of the toy or other-article so as to present a smoothunbroken exterior surface and the article present a highly ornamental appearance without subjecting the uncut or unbroken outer layers of the material to excessive tensile strain.

It is also an object of the invention to provide a method of bending cardboard and analogous material so that all ofthe layers, both creased and lmcreased, will be utilized and will result in .a firm, strong structure containing all of the original material of the cardboard.

A further object of the invention is to provide a method of cutting and forming articles of cardboard by which the elements of the figure of a toy and the mechanical parts will be die cut, blanked out andthe bending creases formed with a single operation;

Further objects and advantages of the method will appear from the following description and the accompanying drawings, in which- Figure l is a plan view of .a sheet of cardboard die cut to form the principal portions of a toy rooster, the crease lines being formed to permit accurate bending of the parts or elements of the toy.

Fig. 2 is an enlarged detail sectional view of a portion of the sheet of cardboard having crease lines formed therein.

Fig. 3 is a similar View illustruing the arrangement of the material-at the crease ni.;- when the cardboard is bent into a curved shape.

i iliig.

analogous material by which the crease lines will' i/cre'ase lines to produce a conical surface on bendl0 ing.

-.Figs 9 and 10 are detail views illustrating the arrangement of a group of parallel curved crease lines to produce a partial torus surface on bend- Fig. 11 is a detail view illustrating a group of divergent curved crease lines to produce a decreasing radius of curvature on bending. t

Fig. 12 is a detail perspective view of a box or container having a plurality of crease lines for forming a hinge for connecting the lid of the box or container to the body thereof.

Referring particularly to Fig. l of the drawings, I -designates a sheet of cardboard or nbre board cut to form iigure elements 2 of a mechanical toy rooster. The mechanical parts 3 and the structural or bracing elements l are die cut out of the cardboard simultaneously with the gure elements of the toy by a single die cutting operation by the use of steel rule dies which will en- 30 able intricate patterns to be easily and cheaply ,e cut from cardboard, fibre, asbestos, wall board and analogous brous sheet material, and 'it will be understood that in the description of the method of the present invention the term' cardboard will comprehend any of such sheet materials.

The gure element which forms the body portion of the rooster is provided with groups 5, 6, l and 8 of parallel crease lines substantially uniformly spaced and adapted to produce relatively broad curved bends and the number of the crease lines and spacing of the same will determine the character of the curve produced by the bending r of the cardboard. 'Ihe crease lines which may 4" be formed by crushing, cutting, scoring or `partial perforation, are located at the inner face of the cardboard or interiorly of the bend so that the outer layers of the cardboard will be unbroken and the inner creased or scored layers will be compressed by the bending of the cardboard, as illustrated in Figs. 3 and-4 of the drawings. None of the material of the cardboard is discarded and al? of the material of the cardboard is utilized in making the bend.

The creased layers which are compressed as shown in Figs. 3 and 4 by the bending automati cally adjust themselves to their new position resulting from the bending and a rm, solid structure at the bend results which is far superior in strength, durability and length of life to material having bending scores or creases arranged exteriorly of the material. When the scored or creased material is bent and the creased or scored layers compressed, the continuous unbroken outer layer is subjected to tensile. strain, but the strain is not sumcient to cause any rupture or other injury to the material which is not impaired, but on the other hand stiiened and supported by the present method of bending.

The depth, number and spacing of the crease lines will determine the shape of the material when bent and the gure element forming the neck of the rooster is provided with spaced parallel groups of score lines 9 having curved portions III at one end of the groups@ The curved portions of the groups converge and produce a taper when the neck piece or element is bent. The groups II, I2 and I3 of the neck piece are .formed in an extension at one end of the neck piece and produce curved surfaces when the material is bent. The crease lines terminate short of the marginal edges of the pieces cut from the cardboard and they may vary in length to form tapering groups I4 and I5, as clearly shown in the figure piece which forms the head of the rooster. The groups of parallel crease lines I6 and I'I are formed in certain of the mechanical elements for producing curved bends of the desired radii or curvature and the circular or cam' shaped pieces which are designed to be built up in the form of a laminated wheel are provided with registering notches I8 cut in the periphery of the pieces to enable them to be accurately assembled.

As illustrated in Figs. 5 and 6 of the drawings the crease lines I9 may be arranged in parallelism at different distances apart to produce compound curves or a plurality of merging curved surfaces having different radii and, as illustrated inFigs.

.'7 and 8 of the drawings, straight divergent crease lines 20 may be provided for producing a conical surface on bending the material. Partial torus surfaces may be produced on bending the materia'l by providing a group of parallel curved creases 2 I, as illustrated in Figs. 9 and 10 of the drawings, and such surfaces may be varied by providing a group 22 of converging or diverging crease lines which results in an increasing or decreasing radius of curvature on bending. It will thus be seen that crease lines of various forms and arrangements may be employed for producing the desired exterior surface on the bending of the material and that such crease lines will cause the material to take diierent forms on bending. A group 23 of parallel crease lines may be `advantageously employed for connecting the lid 24 with the body 25 of a box or container to form a hinge and a hinge of this formation may be employed in toys and various other articles where a hinge action is required. yThe crease lines in the form ofthe hinge 23 may extend entirely across the material which is compressed at the crease lines when the compress the material at the crease1ines- 6. 'I'he method of cutting and forming articles 70 lid is in its closed position.

The present method of cutting articles or parts of articles from sheet material and simultaneously forming bending crease lines therein may be employed in the construction of furniture and various other articles and for bending and shaping building materials such as wall board, and the like.

By the rpresent method the parts are blanked or die cut from a single sheet of material and in the manufacture of toys and other articles the face of the sheet which will be exposed exteriorly of the article may be ornamented prior to the die cutting as intricate patterns may be accurately cut and the bending creases may be formed in the inner face of the material without injuring the exterior ornamented surface. 'I'he cut pieces when bent to the required form may be secured or retained in such form by metal stitches.
